Abstract: There are some wild plants with high values (e.g. Glehnia littoralis and Vitex trifolia) on the sand-beaches of the middle Yellow Sea. The bays connected to the sand-beaches are suitable for swimming and tourism. Every summer, people gather there, causing heavy trampling on the plants. A case study on a sand-beach in Qingdao was conducted to ascertain the effect of human trampling on these plants. The tolerance of the plants to trampling differed: The species G. littoralis, Ischaemum bartatum and Salsola komarovii had the least to tolerance to trampling. Trampling led not only to a reduced grass coverage, but also to a reduction of species richness.
